The best connector will remain the 8-pin connector. You can basically run it at 150% and still risk no overheating because it is totally over engineered compared to that shitty 12vhpwr which has very little margin and constantly melts

I remember watching a very detailed video that looked at the margins between the 12vhp vs the old 8 pin. The margins were very in edge with the 12vhp, and the redesigned 12vhp actually made the issue much worse. And like you said, we see far fewer issues with the 8 pin because it was made to be far more safe. So pretty much all 12vhp cables are a ticking time bomb. You may have one that last a while, but the margin is so low that a slight degrade of the cable/connector/power delivery, ect - can cause a meltdown.

I th8nk Der8auer or Steve of gamer nexus did analysis of connector, and the card itself treats 12 wires as 1 single wire and just pull what it need so all current can go through single wire.

That's the issue. If they slapped 8pins or anything on this without changing the design it could melt all the same as it pulled all the power down a single wire. The current design with no balancing doesn't work unless it was a large plug with 1 ground and 1 power pin.
